About 200 people gathered in Clinton to mark the milestone, reminiscing about some of the more unusual aspects of rural rugby in days gone by.
Cutting the celebratory cake at the Hillfoot Rd clubrooms on Saturday afternoon was longest-serving life member Peter Miller.
Mr Miller was president of the club from 1979 to 1986 and became a life member in 1990.
During his earliest days running out for the club, players needed to be made of stern stuff, the retired farmer said.
"After you’d turned out for the team and muddied up, unfortunately there were no hot showers. In fact there were no showers at all, so players went for a wash in the creek at the back there, which could be pretty hard going with snow coming over the hill."
Mr Miller said he did not manage to attend many matches nowadays, having retired to Balclutha.
Jubilee committee spokesman Tim Grant said the anniversary celebrations had been a big effort for committee members and community volunteers.
"We decided quite late to mark this anniversary, so it’s been all hands on deck since then.
"Obviously, we missed out on the competition at the last minute last season, so it’s fantastic to be able to celebrate the jubilee with our Prems back in the competition."
